I was trying to get the input from Knuckles finger sensors using the axes from native Unity XR input, but it fails to receive any values. Other input axes like trigger/grip work just fine. I used the axes as provided here: https://docs.unity3d.com/Manual/xr_input.html#XRInputMappings (the ones for indexFinger, middleFinger etc.) Does anybody have the same problem, and what may be the cause? I am running this on Unity 2019.2.0f1.
